What this trial studies

This observational study focuses on congenital aniridia, a genetic condition characterized by the absence of the iris and various eye and systemic manifestations. It aims to gather information through a survey designed by ophthalmologists at Hôpital Necker-Enfants Malades, assessing both the patients' understanding of their condition and the range of symptoms they experience. The survey will be completed once by eligible patients or their guardians, providing valuable insights into the disease's impact on quality of life and awareness.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18 and older with congenital aniridia, or minors whose parents can complete the survey.

Not a fit: Patients with neurological disorders that prevent them from answering the survey may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of congenital aniridia and improve patient education and management strategies.

How similar studies have performed: While similar studies on patient knowledge and disease manifestations exist, this specific approach focusing on congenital aniridia is relatively novel.
